How Is Easter's Date Determined? The Spring Holiday Changes Every Year

This year, Easter Sunday falls on April 16. Just last year though, it fell on March 27. If you celebrate the holiday for religious reasons or just enjoy indulging on all the colorful candy, you may be grateful for the extra time to prepare and shop. But you might also be wondering, "how is Easter's date determined," and "why does it sometimes land in different months." Well, it has to do with both the Gregorian calendar and the moon.
